GREAT Helpful Hint!!!

I'm pretty sure a lot of you are aware of this but wanted to "educate" those who aren't. I have a Yong Heng compressor and am in the habit of bleeding the moisture trap on the YH for a few seconds every 5ish minutes of run time. I lose ZERO pressure from the tank I'm filling because of a ONE WAY CHECK VALVE foster fitting. Pressure in the tank forces the one-way closed while I bleed moisture so I ONLY lose pressure in the hoses & filters, NOT THE TANK. I think I paid $6 for it (Amazon) but it's saved my compressor a lot of extra work. Saw this hint in a video a couple years before getting my YH but one of the best helpful hints I've put to use. No having to quickly shut down tank valve before stopping the compressor. They are to be found CHEAPLY on Amazon or Ebay. Hope this helps! Stay safe & shoot straight! 
 
Similar here. I had an adapter for filling at a fire house for my Great White but have since added a one way check valve to that adapter for use during filling only with my compressors. I simply remove the check valve adapter and put in my original foster adapter after filling the tank and going to the guns. Takes just a few seconds to exchange the two.
 
I personally use 6000psi 2 way inline check valves.

Just connect tank to compressor then open the valve full throttle then (After warmed up) restart the compressor since there's zero load coming from the tank side with the 6000psi 2 way check valve in between.

Jking makes them. Highly recommended For $65.00 - $70.00 each.

They are rated at up to 6000psi but doesn't require 6000psi to flow. You can go a lot lower and won't stress your compressor.
 
I am still a relative newbie so please forgive me if I am totally off base with this, but could you attach the one way male check valve foster fitting to a female foster quick disconnect and attach the female end to a male foster of the tank (essentially a male to female standalone adaptor)? My tank only has a male foster that then attaches to a double female hose that I got from Joe Brancato. If that worked, it would be a very convenient and quick connection for only filling the tank. Thanks.

You can try to bring the male foster high pressure check valve with that (JB) hose to your local high pressure hydraulic air hose shop to have them install a collar to match the threads to screw it right onto one end of the hose.

HMMM... THAT song reminds me of THIS-
